my experience is the 22-250 is hard on chamber throats even with flat based bullets... ( I have a Remy 700 I'm re-barreling / re-chambering to 6.8 SPC, as the throat was shot out, & I can pretty much bet it never had a BT bullet down the barrel )
what you are saying likely makes sense, though I don't know of any studies done specifically on that cartridge
